how to damage copies of 1 enemy with
i have solved it by myself by learning python and making new system, using this script. anyway thx for  answers...

from bge import logic as GameLogic
c = GameLogic.getCurrentController()
own = c.owner

enemydetect = c.sensors["enemydetect"]
punchright = c.sensors["punchright"]
if punchright.positive and enemydetect.positive:


    obj = enemydetect.hitObject

    obj["HP"] = obj["HP"] - own["RightDamage"]
